PARIS: The presidents of Russia, the United States and France called Thursday for a ceasefire in the Nagorny Karabakh region, urging Armenia and Azerbaijan to commit to talks without delay or preconditions.

"We call for an immediate cessation of hostilities between the relevant military forces," French President Emmanuel Macron, Russian counterpart Vladimir Putin and Donald Trump of the US said in a statement released by the Elysee.

"We also call on the leaders of Armenia and Azerbaijan to commit without delay to resuming substantive negotiations," said the leaders, whose countries are the co-chairs of the OSCE Minsk group that has sought a solution to the conflict since the 1990s.

The statement said such taks should be "in good faith and without preconditions" and be held under the auspices of the OSCE Minsk Group co-chairs. The Minsk group, which was created by the Organization for Security and Co-operation in Europe (OSCE) in 1992, has on occasion overseen summits between Armenian and Azeri leaders but has failed to find any lasting resolution to the conflict.

The fiercest clashes between Armenian and Azerbaijani forces in years over the region erupted last Sunday. The number of confirmed deaths neared 130 as fighting raged for a fifth day.
